Hi Adam thanks for you prompt reply, I thought I had upgraded everything to g5x when it was first released, should I do an ecu upgrade?

I have decided to add Link CAN Lambda to my ECU, to do this I had to open the unit and connect the CAN cable to CAN1 So after installing the CAN lambda kit but before connecting the CAN lambda to CAN1 I powered on the LINK ECU and i got a successful connection than a series of errors Injector 1-4 out of range then a list of issues. Any ideas what has happened? the only thing I can think of is a bad ground connection

Hi Adam have you had a chance to look at this? cheers

Hi Adam I have just added a termination resistor and it made no difference. Is there a particular parameter(s) you want me to log? or specific log file? I have uploaded a CAN log, Starts off error free, then I attempt to connected with OBD2 adapter ~18secs and then reset the CAN at ~47secs PC Datalog - CAN reset after OBD2 connection.llgx

Hi Adam Here are the files you requested. As you can see from the logs the ECU just stops responding unless I reset the ECU. Cheers Subaru WRX V3-4 -5.22.pclx Restart ECU after connection hack.txt Failed to connect log.txt Connected but failed to operate.txt

Hi again I tried some other adapters and tried some other software but with no luck but I did make some progress. While trying to connect with different software and different adapters I discovered I could connect but only within a second or two of the ecu powering up, if I didn’t connect during this time the adapter would never connect. so typically I would attempt to connect with this sequence Plug in adapter power up ecu connect to adapter using car scanner app attempt to connect to the ecu. this always failed unless I also connected to the ecu with my computer and and scanned the CAN bus as described above. so my new sequence was like this Plug in adapter connect to adapter using car scanner app attempt to connect to the ecu power up ecu this sequence worked is as long as I attempted to access data within a couple of seconds of the ecu powering up otherwise it would not work. Although this is a workaround it is not very convenient. If I then disconnect the ecu in the app and reconnect the connection will fail. it seems to me that the CAN bus looks for data traffic during ecu startup and if it doesn’t find any it simply stops listening to the CAN bus. My Can Scanner app allow me to send command is there an initiation command I can send the ecu to wake it up? Is there a CAN bus timeout that can be set longer than a couple of seconds?

Thanks your help, I will give it a go. The OB2 reader is the only thing on CAN2, would I need to add a termination resister to the loom? thanks

Hi Adamw, The bit rate is set to 500k, once again it works OK once the two devices start talking. I've attached the map to the the original post

Hi Team I am having issues with OBD2 scanner connecting to my G4X V4 WRX Plugin ECU. My scan tool has 3 LEDs: Red-Power, Green-network, and Blue-Bluetooth. It is wired up to CAN2 and the OBD has be set to "ISO 15765 on CAN 2" in CAN setup. But with this setting turned on nothing happens (only the red & blue LEDs and the slow green polling flash) UNLESS I click the "CAN Devices" tab and click "Find Devices" button. As soon as I do this the OBD2 scanner comes to life (Fast flashing green led) and Scanner works perfectly as expected. Obviously having to connect my PC and click the "find Devices" button every time I want to use the OBD2 is self defeating, is there any setting that I have missed? If not, can I make CAN2 transmit something to wake everything up? Subaru WRX V3-4 -5.22.pclx
